Subject: REDIRECT in nat OUTPUT
Date: Sat, 12 Jul 2008 04:24:56 +0300 [thread overview]
Message-ID: <200807120424.56462.denys@visp.net.lb> (raw)
I notice TX performance issues while using REDIRECT rule in -t nat -I OUTPUT chain.
To reproduce:
First let's test network and HDD speed
homecore ~ # scp PSA_schematique_07H.iso root@127.0.0.1:/tmp
PSA_schematique_07H.iso 7% 335MB 25.7MB/s 02:39 ETA
^C
Killed by signal 2. (i kill it)
Second let's do the trick
iptables -t nat -I OUTPUT -p tcp --dport 23 -j REDIRECT --to-ports 22
scp -P 23 PSA_schematique_07H.iso root@anyhost:/tmp
PSA_schematique_07H.iso 0% 8728KB 121.3KB/s 10:22:05 ETA
^C
Killed by signal 2.
Always all rules with REDIRECT to local port is dropping speed around 100Kbyte/s. What can be the problem?
